Earlier, Tumgoev was detained twice - in Kyiv, before leaving for Kharkiv, and upon arrival in Kharkiv, where the court was to be held. When detained, he was charged with an expired certificate of an asylum seeker.

Tumgoev appealed to the migration service of Ukraine with a request for asylum, and a certificate is a document proving his identity. He was detained by the Ukrainian border service at Kharkiv airport in June 2016, where he arrived from Turkey. In July 2017, he was released from custody after the expiration of the extradition arrest.

The FSB of Russia suspects Tumgoev of participating in one of the radical groups in Syria. The General Prosecutor's Office of Ukraine then decided to extradite Tumgoev. The European Court of Human Rights twice refused to suspend the extradition, but the UN Human Rights Committee obliged the Ukrainian authorities to suspend the extradition.
